7. Kochia Roth
species, North America, Europe, Asia, Africa.
The genus Kochia
is closely related to Bassia All. and also to Cycloloma. All
three genera have outgrowths of various sorts on the sepals. Some botanists have
combined Kochia and Bassia under the latter name (Scott, 1978;
Clemants, 1992; Judd and Ferguson, 1999). However, the phylogenetic
relationships among these groups require more detailed study, and the three
genera (only two of which occur in Missouri) are here maintained as separate.
